How does a rise in temperature affect the Heart Rate Blood P

Solution

An increase in temperature causes the heart to beat faster , as body needs more blood to cool itself down.

High temperatures causes vessels to dilate, and hence blood exerts low pressure on their walls, and blood pressure decreases.

High temperature causes increase in respiration, as all the biomolecular reactions increase their rate in the body and cellular respiration increases.

Pulse oximetry decreases during rise in temperature and vice versa for low temperatures.
